Specification of Letters Patent.

Application filed January 4, 1916. Serial No. 70,221.

To all whom it may concern Be it known that I, GEORGE H. RUMKE, acitizen of the United States, residing at Denver, in the county ofDenver and State of Colorado, have invented certain new and usefulImprovements in Amusement Devices, of which the following is aspecification.

This invention relates to new and useful improvements in amusementdevices of the type commonly known as motordromes, its object being toprovide in association with suitable operating mechanism, an annularmotordrome which is pivotally mounted to be moved about a determinateaxis out of the plane in which it is normally disposed.

A motordrome thus constructed is as a means for affording entertainment,a decided improvement over the stationary dromes at present in use,since it permits of raising the endless riding surface along which avehicle is being driven, to any angle from the horizontal to theperpendicular without interrupting the performance.

With the above object in view, my in vention consists in the-features ofconstruction and arrangement of parts shown in the accompanying drawingsin the various views of which like parts are similarly designated, andin which,

Figure 1 is a sectional view of my improved motordrome, Figs. 2, 3, 4and 5 similar views showing motordromes of modified construction, andFig. 6, a plan view of the construction shown in Fig. 1.

Referring first to Fig. 1 of the drawings, the motordrome consists of anannular trackway 2 made in any desired manner and of any suitablematerial which interiorly has a riding surface 3. The riding surfaceextends transversely at substantially right angles to the horizontal,and a supplemental inwardly inclined riding surface 4 of reduced widthadjoins the main riding surface at its lower edge to provide an approachalong which a vehicle driven within the trackway may gradually ascend.The annular trackway is normally supported upon a level foundation 5 andis hinged as at 6 to be moved throughan arc of approximately ninetydegrees. A bail 7 applied adjacent the upper edge of the trackway atpoints opposite to that at which it is hinged, is attached to apull-rope 8 which running over an elevated sheave 9, is at its oppositeend either connected with a Windlass or main riding surface ispositioned transversely at right angles to the perpendicular. Thevehicle now moves in an upright endless course to which it is held bycentrifugal force, and it continues performing this extraordinary featuntil the annular trackway is again lowered to its normal horizontalposition when the vehicle may gradually descend onto the approach andacross the same onto the floor upon which the drome is supported.

In the form of my invention shown in Fig. 1, the annular trackway isopen at the top and bottom so that when it is moved to an uprightposition, the performance may be observed from opposite sides of thesame.

In the form illustrated in Fig. 2, the trackway forms an integral partof a floor 12 and the performance can in consequence be seen onlythrough the open top of the runway is transversely straight, while inthe modification illustrated in Fig. 5, it is transversely concave. Atrack of this character is particularly adapted for motorcycles whichcan be driven onto the upright surface without the aid of a taperingapproach such as is used in the first-described preferred form of myinvention.

Having thus described the construction and operation of my improvedmotordrome, I desire it understood that any suitable means for thepivotal supportof the annular trackway or for moving the same through adeterminate are, may be used Within the spirit of my invention as setforth in the appended claims.

I claim 1. In a motordrome, a trackway having a riding surface and aninclined approach, said trackway being movably mounted for effecting apivotal movement of said surface about a determinate axis.

2. In a motordrome, the combination with a surface, of a trackWay havinga riding-surface, and an inclinedapproach between said surfaces, thesaid'trackway being pivotally mounted for moving said ridingsurface to aposition at an angle to the other surfaces.

3. The combination with a supporting surface, of a motordrome composedof an annular body provided With an internal riding surface, normallysupported upon the first-mentioned surface and mounted for movementabout a horizontal axis fixed with relation to the same.

4-. The combination With a supporting surface, of a motordrome composedof an annular body provided With an internal riding surface, and mountedfor movement about a horizontal aXis fixed with relation to the same.

5. The combination with a supporting surface, of a motordrome comprisingan annular body having an internal riding surface which from the linealong Which it adjoins the first mentioned surface extends in asubstantially straight line at right angles to the same.

In testimony whereof I have a'fixed my signature in presence of tWoWitnesses.

GEORGE H. RUMKE.
